A ADAM WINGARD, OF SAN FRANCISCO, CALIFORNIA.

Letters Patent No. 99,7510, dated February 1, 1870.

IMPROVEMENT IN PADDLE-WHEELS.

The Schedule referred to in these Letters Patent and making peut of the same i To all whom it mag/'concern Be it known that I, ADAM WINGARD, of the city and county of San Francisco,-Sta'te of California, have invented an Improved Paddle-W heel; and I do hereby declare the following description and accompanying drawings'are sufcient to enable auyperson skilled in the art or science to which it Amost nearly'appertains, to make and use my said invention or improvements without further invention or experiment.

My invention relates to paddle-wheels for vessels which are driven through the water by steam-power.

The object which it is desiredrto'accomplish by this invention, is to so construct and arrange the buckets or oats. ofa paddle-wheel, that there will be little or no'loss of power in driving them through the water, occasioned by the pounding and lifting of the Water, which is supposed to exist when the paddle-wheel is provided with the ordinary transverse iioats; and t It consists `in constructing the-paddle-wheel of one or more wheels, each one of which is provided with arms or spindles, secured to a central hub. These wheels Iare securedupon a shafta't the proper or required distance apart. The. extreme outer end of the spokes or arms is turned or *made smaller than the arm itself, so as to form an alvle, upon which. are placed the floats or buckets.

The buckets consist -oftwo centralfhubs, having three radiating wings standing in such a position that theanglc formed between each two is an obtuse an gie, and which I call tripartite buckets.

In order to give a better illustration of my invention, reference is had to the drawings accompanying.

this specifica-tion, and forming part of the same, in which the same letters of reference indicate identical parts wherever they occur.`

A is the shaft, to which the paddle-wlieel is attached, and with which itrevolves.

B B B are three hubs attached to the shaft A, at

i the proper or required distance apart.

Secured in these hubs, and radiating from them, are arms or spokes C C C, their extreme ends being united y by a metal hand, I), which serves to strengthen and` keep the spokes in their proper position.

Other bands may be employed at suitable distances from the hubs, when desiredto give greater strength to the wheels.

The outer end of 'each of the spokes or arms C is made smaller than the arm itself, so as yto forma jour,-

nal, a, of sucient length to receive the buckets or oats.

The buckets consist of three radiating wings b b b, of the proper or desired length, united by boxes d d at each end. These wings taper toward' their outer ends. and are arranged about the hubs, so that the of these tripartite buckets or iioats is placed upon the A journal a, on theend of each of the armsC, so as to revolvev loosely about it, a small nut or projection, e,

serving to prevent theV float from coming in contact with the band or rim l).

One or more of these wheels can be used to form one paddle-wheel; but when I employ moiethanone, I arranget'he buckets or iioats so that they will alternate; 'that is, each float is placed so that it willbe betweenthe two oats on the wheel next to it on either side, as shown, thus enabling the buckets to act upon the entire width of water, without piling it up, so as to impede the following buckets, especially'ast-hey emerge -or rise out of the water.

Aws the wheel revolves, the buckets have no fixed ruleor position, but turn as the motion of the wheel induces them; but when they strike the water, one

of thefwings b,'acting as a rudder, causes the other twowings to stand, so as to present a V- shaped open;

ingor trough to engage the wat-er.

As before stated, the wings b b taper toward their outer ends, thus 'allowing them to enter the water with less force than if they were Vfot' equal width theirentire length; while, attent-hey have become submerged, the greater width `of the upper end causes .them to ha-vefull force at the exact point where it is most required, that is, in-making the sweep of the lowest `part 0I" the circle.

At the junction of the wingsfwith the axle, small l"lfc'ingitudinal slots are made between the two boxes,

upon which the buckets turn, which allow any air, which may become confined in the trough of the buckets' by heilig suddenly forced into the water, to escape, thus preventing a rebouud'when the bucket strikes `the water. v 4

In emerging from the water, the buckets will 'relieve themselves of the weight of wat-er in the trough,I the motion ofthe wheel and driving of the waves, when the vbucket has partly emerged, causing it to revol've and .discharge the water, and in suddenly reversing the motion of the wheel, should it be -caught when the crank is on the dead-centre, the buckets will not yimpede its movements in any manner, but will lturn to the proper position to act in the opposite diallowing the engine to exert the greatest amount of B B, eztoh of said hubs being provided with radiating force it is capable for the amount of power employed.

Having thus described my invention, v That I claim, end desire to secure by Letters Patet, is`

1. The tripartite consisting ofthe tapering wings b b b, with their boxes v 11d,`e`ach bucket revolving upon an axle, a', substantiztlly as and for the purpose herein described.

2. A paddle-wheel, composed of one or morel hubs or three-parted buckets or Heats;

arms C C, and each arm being provided with a tripartite bucket, similar to that herein described, substandell y as herein set forth.

In' witness whereof, ,I have hereunto set my hand and seal.
